The Centers for Medicare & Medicaid Services (CMS) published a proposed rule on March 4 to help patients more easily access their complete health information in interoperable forms across programs that CMS administers (the Interoperability Rule). In the rule’s preamble, CMS lays out a vision of an environment in which a patient’s health information can move seamlessly between health plans, providers, and post-acute care settings. CMS observes that while adoption of electronic health records (EHRs) by healthcare providers has been significant, progress on interoperability needs to be accelerated. The Interoperability Rule fact sheet is available here. While there are several new proposals and requests for information in the 71-page document, this post provides an overview of two of the Interoperability Rule’s proposals.
